摘要
在低速时,电压模型测量不准确,对电励磁同步电动机磁链观测需要使用电流模型。本文讨论了基于磁链幅值给定和基于定子电流两种电流模型,给出两种电流模型的基本原理和控制框图,并在Matlab/Simulink平台上对两种电流模型磁链观测器仿真研究,比较分析仿真结果,得到各自优缺点。
The voltage model flux measurements are not accurate at low speed. We need to use the current model flux electrical excited synchronous motor. This article has discussed two kinds of current model flux observer which are based on the given value of flux amplitude and stator current. Given the basic principles and control diagram of two current model. Simulated there two current model in Matlab / Simulink platform. Finally analyzed the simulation results, and found their advantages and disadvantages.
